In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/watchdog/alim7101_wdt.c: In function ‘fop_ioctl’:
drivers/watchdog/alim7101_wdt.c:279:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
wdt_keepalive();
^~~~~~~~~~~~~~~
drivers/watchdog/alim7101_wdt.c:282:2: note: here
case WDIOC_GETTIMEOUT:
^~~~
Notice that, in this particular case, the /* Fall through */
comment is placed at the very bottom of the case statement,
which is what GCC is expecting to find.
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.

I added it to my watchdog-next branch. Usually Wim will pick it up from there.
